Recording the Clifton Scale

Roland Trim from Arup and I recorded the “donging” of 30 suspension rods on Clifton Suspension Bridge. I”donged” each suspension rod or hanger with a rubber ball starting with the longest (20 Meters)by the tower and moving to the shortest in the middle (about 50cm). Roland recorded each”dong” with an accelerometer – a sensor that measured the vibrations.  He then took the recordings back to his studio and transformed them into wav. files.  This is just one of the many sound tests in preparation for our first Human Harp bridge performance in Bristol Summer 2015 (Bridge illustration by Alessia Milo)
